what means difficult? I'm willing to invest in this,
if it's possible at all.

Ok, as I said, I'm not an ArcGIS expert. Some years ago, as
I looked deeper into it, gdal was an option for
reading rasters. Nice to hear that this has changed.
I had the illusion that this could solve the spatialreference
problem, but this doesn't seem to be the case.
